SECTIONAL SASH-WEIGHT.

Specification of Letters Patent.

Patented Nov. '7, 1905.

Application filed October 21, 1904. Serial No. 229,512.

To (all whom [It may concern:

Be it known that I, NICHOLAS A. PETRY, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Sectional Sash-l/Veights, of which the following is aspecification.

My invention relates to that class of sashweights which are composed ofa series of sections or members connected together, the object of myinvention being to so construct such a sash-weight as to provide themaximum of weight in each member, to render unnecessary any finishing ofthe engaging portions of the members after they leave the mold, and toprovide simple and efficient means for hanging the weight.

In the accompanying drawings, Figure 1 is a view, partly in sideelevation and partly in section, of one member of a sash-weight and partof another member constructed in accordance with my invention. Fig. 2 isa transverse elevation, partly in section, of one of the weight members.Fig. 3 is a View illustrating a modification in the construction of theconnecting portions of the weight members.

The various sections or members of the weight are all alike, so that nospecial selection is needed in fitting them together. Each weight memberconsists of a body portion 1, preferably of rectangular cross-sectionand having one end beveled, as shown at 2, this beveled end having aprojecting hook 3, which is of less width than the weight member asshown in Fig. 2. The other end. of the weight member has formed in it ah ook-sh ap ed recess 4, open at one side and bounded by lateral cheeks5 5, as shown in Fig. 2, that portion of the weight member whichprojects over the hook-shaped recess having formed in it a verticalopening 6, which occupies a central positionthat is to say, a positionmidway between the four sides of the weight member.

In fitting the successive members of the weight together the memberwhich is to be hung is held in-an inclined position, so that the curvedhook 3 can. enter the mouth of the hook-shaped recess, as shown bydotted lines in Fig. 1, this relation of the weight members beingpermitted by the beveled end 2.

After being adjusted to the position shown by dotted lines in Fig. 1 theweight member which is bein hung is swung down into line vertically witthe member above it, so as effect engagement of the hook 3 of the uppermember with the overhanging portion of the recess 4 of the lower member,as shown by full lines in Fig. 1, the bearing-points of the hook andoverhang being in the central vertical plane of the weight members, sothat they will hang perfectly straight, and therefore will not come intocontact with the sides of the weight-casing of the window-frame.

The hanging of the weight is effected by simply passing the lower link 7of the suspension-chain through the opening 6 in the topmost member ofthe weight and then engaging with the inner end of said link a splitring 8, contained in the hook-shaped opening 4, as shown in Fig. 1, orif a rope is employed for the suspension of the weight the lower end ofsaid rope may be passed through the opening 6, drawn out from the recess4, knotted and then drawn into said recess 4, the knot being of suchsize that it cannot be pulled through the opening 6.

In that embodiment of my invention as shown in Fig. 3 the shape of thehook 3 and of the recess 4 is slightly different from the correspondingparts 3 and 4 of the weight member 1, and the adjoining ends of bothweight members are partly straight and partly beveled; but thesedifierences are immaterial and do not affect the objects of myinvention.

It will be evident that in sash-weights constructed in accordance withmy invention there is very little loss of weight due to the constructionof the engaging portions of the weight members, this loss beingrepresented by the beveling of the weight member or members and beingmuch less than in any other form of sectional sash-weight with which Iam familiar.

Having thus described my invention, I claim and desire to securebyLetters Patent- 1. A sectional sash-weight member having at one end ahooked recess closed at the back, and at the other end a correspondingprojecting hook, said member also having a beveled portion or portions,whereby angular adjustment of adjoining members is permitted in enteringthe hook of one member into the recess of the other from the front ofthe lat ter, substantially as specified.

2. A sectional sash-weight member having at one end a hooked recess with.side cheekpieces lying parallel to the plane of said recess, and at theother end a projecting hook less in width than the weight member, saidIIO member also having abeveled portion or poring for the reception ofthe suspension rope IO tions, whereby angular adjustment of ador chain,substantially as specified.

joining members is permitted in entering the In testimony whereof I havesigned my hook of one member into the recess of the name to thisspecification in thepresence of 5 other, substantially as specified. twosubscribing Witnesses.
